The Five People You Meet in Heaven by Mitch Albom (e-book)
Eddie is a wounded war veteran, an old man who has lived, in his mind, an uninspired life. His job is fixing rides at a seaside amusement park. On his 83rd birthday, a tragic accident kills him as he tries to save a little girl from a falling cart. He awakes in the afterlife, where he learns that heaven is not a destination, but an answer.
